Add ActiveX Tabs to Model View Example (C#)

This example shows how to add two ActiveX tabs to a model view.

//----------------------------------------------------------
// Preconditions:
// 1. In the IDE, reference your ActiveX control file
//    (click Project > Add Reference > Browse and browse
//    to the folder where the ActiveX control resides and click
//    the ActiveX control file > OK).
// 2. Verify that the specified part document exists.
// 3. Replace activex_control_component_declaration and
//    activex_control_CLSID_or_ProgID with your ActiveX control's
//    information.
//
// Postconditions:
// 1. Opens the part document and adds two new tabs to the model view.
// 2. Activates the model view.
// 3. To verify the ActiveX controls on the new tabs, click each tab.
//
// NOTE: Because the part document is used elsewhere,
// do not save changes.
